The Delirium Motor Subtype Scale (DMSS) was developed to capture all the previous different approaches to delirium motor subtyping into one new instrument and emphasize disturbances of motor activity rather than associated psychomotoric symptoms. We investigated reliability and validity of the DMSS Dutch version. Elderly patients who had undergone hip fracture surgery received the DMSS and the Delirium Rating Scale Revised-98 (DRS-R-98). A diagnosis of delirium was defined according to the Confusion Assessment Method (CAM). Among 146 patients, 46 (32%) patients were diagnosed with delirium (mean age 86.3 years; SD 5.2). The internal consistency of the DMSS was acceptable (Cronbach's alpha=0.72). If an item was removed at random the internal consistency of the scale remained the same. Similarly the concurrent validity of DMSS was good (Cohen's kappa=0.73) while for each motor subtype the Cohen's kappa ranged from 0.58 to 0.85. The sensitivity and specificity of DMSS to detect each subtype ranged from 0.56 to 1 and from 0.88 to 0.98, respectively. This study suggests that the Dutch version of the DMSS is a reliable and valid instrument. The DMSS has scientific validity that could allow for greater precision in further research on motor subtypes.
谵妄运动亚型量表（DMSS）旨在将之前所有不同的谵妄运动亚型分类方法整合到一个新的工具中，并强调运动活动的紊乱，而不是相关的精神运动症状。我们研究了 DMSS 荷兰语版本的可靠性和有效性。接受髋关节骨折手术的老年患者接受了 DMSS 和修订后的 98 项谵妄评定量表（DRS-R-98）的评估。根据意识混乱评估方法（CAM）对谵妄进行诊断。在 146 名患者中，46 名（32%）患者被诊断为谵妄（平均年龄 86.3 岁；SD 5.2）。DMSS 的内部一致性是可以接受的（Cronbach's alpha=0.72）。如果随机删除一个项目，该量表的内部一致性保持不变。同样，DMSS 的同时效度也很好（Cohen's kappa=0.73），而对于每种运动亚型，Cohen's kappa 的范围从 0.58 到 0.85。DMSS 检测每种亚型的敏感性和特异性范围分别为 0.56 到 1 和 0.88 到 0.98。这项研究表明，DMSS 的荷兰语版本是一个可靠和有效的工具。DMSS 具有科学有效性，可以在进一步研究运动亚型方面提高精度。
